Electromagnetic interference (EMI) and radio frequency interference (RFI) are common troubles in today\'s electronics and electrical systems and have become one of the main sources of system malfunctions. To mitigate this problem, EMI/RFI filtering networks, such as LC (inductance/capacitance) and RC (resistance/capacitance), are utilized. LC networks are most commonly used in power systems and are found to be very effective in blocking common mode EMI noise. The MEA2010LC220 is a type of LC filter network designed to provide high performance EMI/RFI suppression.

The MEA2010LC220 is a general purpose EMI/RFI filter network designed for use in low voltage power applications such as domestic power sources, audio systems, power supplies, and other industrial applications. It is designed to filter and suppress noise that may be present on the AC power lines. The MEA2010LC220 consists of two identical, two-stage LC filter circuits enclosed in one housing. Each filter circuit consists of two inductors and three capacitors, making the total size of the filter small enough to fit into limited spaces.

The MEA2010LC220 works according to the principle of low pass filter networks. It is designed to be connected on the input side between the AC power source and the power load, or on the output side between the load and the ground. Its filter circuit creates a low impedance path to ground and a high impedance shunt path to the power line, isolating the load from the power source. It also creates a differential mode impedance which determines the frequency of noise that can pass through the filter and reduced amplitude of the noise. The main purpose of this filter is to suppress the higher frequency, common mode noise signals while allowing normal AC power to pass through the filter without any disruptions.

The MEA2010LC220 is specially designed to provide optimal EMI/RFI suppression for its intended applications. It is rated for line voltages up to 220V and frequencies up to 50kHz, making it a good choice for many industrial applications. Its small size and the ability to be installed in a variety of positions make it an ideal choice for many installations. The MEA2010LC220 is an effective and reliable EMI/RFI filter network that can provide high performance EMI/RFI suppression for low voltage power applications.
